This is a tempest bug - but the test creates a server, starts a snapshot and then waits for the server to have the "ACTIVE" state. There is waiting for the image to have finished uploading - but the instance may not have been returned to the "ACTIVE" state immediately.

    Race condition in ListImageFilters tests

    The server may not have moved back to ACTIVE state for
    a short period after the image has been successfully
    uploaded - so wait for the server to be ACTIVE
    before continuing with the tests
